Answer:

limpet

Explanation:

This has a single, "limpet-like" shell on top, which is made of proteins and chitin reinforced with calcium carbonate, and is secreted by a mantle covering the whole upper surface. The underside of the animal consists of a single muscular "foot". Although molluscs are coelomates, the coelom tends to be small.

crustal formation,which may cause the widening of an ocean is most likely occurring at the boundary between...?
balandron [24]

Divergent boundary.

This is the boundary between two tectonic plates move away from each other in opposite directions.

Explanation:

One major example of a divergent boundary is the mid-Atlantic ridge that cuts, longitudinally, across the middle of the Atlantic ocean.

When two tectonic plates move away from each other in opposite directions, the void they leave in between is filled by rising magma from the mantle and cooling to create new crust. A mountainous ridge along a boundary is evidence of a divergent boundary. The Atlantic ocean will therefore continue to widen as the North American and Eurasian Plates move away from each other. As new crust is formed at divergent boundary, old crust is being consumed at convergent boundary on another end of earth. This way tectonic plates of earth renew themselves.
